` IRRIGATING 4VAityn Be it` known that I, GnoRGnC'. l/IA'RTIN, a citizen of the United States', and a'resident of Los Angeles, in vthe county of Los Angeles, 'State of California, Vhave invented Myinvention relates tov and has for an object the provision of `certain improve-i ments indrrgating valves such as Vare used in irrigating systems for orchards and the like, and consist mainly in means for mounting the valve stem and T on the valve lid, whereby the `lid maybeV raised `and lowered with' facilityk relative to the arch member which constitutes the valve mounting vfor the standpipe. Other objects may appear as the description progresses.

I have shown onepracticalY embodiment of my invention inthe accompanying vdrawings, in which.: y

Fig. 1 is a plan view of the valve apart from its support. j A y y f Fig. 2 is a bottom plan view ofthe same showing particularly means for locking the valve stem bushing.` *Y

Fig. 3 is an enlarged section of said locking means.

Fig. 4 is an elevation of my valve, partly in section. l f v Fig. 5 is a sectional elevation of a water pipe and standpipe with my valve shown attached thereto for use.

I will now describe 'my improvements in connection with a well known type of irrigating valve, now in general use, reference being had to the drawings hereinabove mentioned.-

Referring to Fig. 5, a main irrigating pipe, or lateral P vis shown in section withA a standpipe S attached thereto and in communication therewith and a valve mecha-` nism V mounted at the upper end of the standpipe. An outlet O is attached to the upper end of standpipe S and carries one or more gate valves G. This structure is common to such systems and isshown only for illustrating my improvements.

Valve V consists of a mainsupporting member 1, having an annular portion adapted to seat on the end of the pipe S and a depending central rib', or arm 2 which spans the opening 3 within the annular neck 4 of said supporting member. A lid, or closure 5 of disc-like character is arranged Specification of'Letters Patentr" p Pgrentedkpl.: '1922.

N f y centralportionl'7 of thelid isi-bored .to receive an extension S'of the T19, a flange '10 is formed on said T for aifordi'ng anabu't- The ment, and a washervll` is providedonthe lowerend of extension '8 for engagementr with and to hold the gasket 6 ont'he lid.

The upper portion ofthe 1T is cored toire-l ceive the end of the valve stem 12 and the lower portion thereof is threaded toV vreceive an'externally threaded bushing 13 which has a a slightly enlarged head 14 on its end, said` 'bushing beingv flattened as.` at V15, 15 ron opposite sides, .jas shown vin 2 and 4. A'lock washer v16 is held between the' head v'14' of saidl bushing and the-end of vextension 8 and has a 'square opening 17 therethrough 'i which fits over the flats of the bushing, and

the periphery'gof the lock washer substan-V tially overlaps the washer 11, and gasket,

as shown. When the bushing 13 is tightened" in the vT by suitable means the same is f adapted to be locked against'turning by means of lips 18, 18 formed vontheinner v8.5

portion of the lock washer l'adjacent to the Hat sides l5 of the bushing. Said lips are forced inwardly into recesses 19, 19 in the end of extension 8 of the T,as shown in Fig. 3 and thus the bushing and T are locked against accidental separation in use. The valve stem 12 is carried in the central portion of the arm 2 and has a head 20 onV i i its lower end and a lock nut 21 above theportion 22 of said arm, .and is thus `rendered stationary inits support. l This vvalve stem preferably has a square thread and. is

threaded through the bushing 13 which has The operation of the valve is well underk105 stood. The T 9 is rotated manually on the stem 12 and the .lid 5, gasket 6, washer 11 and bush1ng13 rotate therewith at all times,

.the said members being elevated or lower relative tothe neck 4, according to the vdirection in which they are turned, and the pipe prevent rusting and the consequent dif-` long y Said bushing is S is opened orfclosedkas the case may be, correspondingly.

What l claim, is: y f

l. In an rrigating valve, a` stationary valve stem, .a closure member operable there on and including an operating member having a threaded bushing thereimand means intermediate said operating member Vand said bushing for rendering the bushing movable with said closure. y

2. ln an irrigating valve, avalve stem, a closure member having a handle thereon and movable relativel to said stem, a bushing of non-corrodible material held on said closure and threaded to receive said stem, and a locking member carried on said bushing and having means engaging a portion of said closure member, for effecting the simultaneousV movement of said. bushing and said closure member.

3. An irrigating valve including relatively movable valve stem and closure members, a

. bushing carried in said closure member and threaded to receive said stem, and a locking i. disc held between a portion of said bushing and said closure member' and having means 'for locking said elements together for use.

4. An irrigating valve Yincluding a valve support, a relatively movable valve stem and closure held thereon, a bushing held on said closure'4 and threaded to receive said stem, said bushing having an enlargement at one end, anda locking disc held on said bush- Y iai/ipsil l i ing and between said enlargement and said closure and having portions seating in said. Closure, for the purpose described.

5. An irrigating valve having a valveI stem and a closure movable thereon, a T attached to said closure, a bushing threaded into said T and having iiattened portions. on its periphery, a vlocking member having an opening with flat sides engaging the flattened portions of said bushing, said T having recesses in the end thereof, andsaid locking` member havinglips adapted to seat in said recesses, `lfor the purpose described.

6. An irrigating valve having a valve stem and a closure. movable thereon,` a bush-l ing threaded into a portion of said' closure and internally threaded to receive said valve stem, said bushing having flattened portions on its periphery and/an enlarged head, a locking member carried on said bushing and having a rectangular opening therein'to receive said bushing and engaging said irlat` tened portions, said closure having recesses formed adjacent to said locking member, and said locking member having lips adapted to seatvin said recesses, for locking said bushing and said closure together' for operation GEORGE C.
